ISAAC rV'. IBIIILYEU, OF SPRINGFIELD, ILLINOIS.

To all whom t may concern Be it known that I, ISAAC V. BILYEU, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented certain new The principe Object' of. the invention is to provide movab frog lates each carrying y sections of straight rails and curved rails,

the former of which are adapted-to connect with the main straight lines, while,` the latter of which are adapted 'to register with curves leading to the right or to the left coming Vfrom either direction.

The invention consists of two transversely "slidable plate members, carrying a straight 'section and two curved sections of rail on each end, said plate being adapted for slidable movement in opposite directions, so as to get the following combinations: The train may move straight along the vmain track; the train vmay pass from the main track to the right or to the left coming in either direction; the train may be coming around one of the curves from either the right or the left from either direction, and either continue around the curve in 'the same direction, or cross the main track and continue around the curvein the opposite direction.

In the accompanying drawings: Figure 1 is a plan View of a railroad track showing my invention applied andin position to permit a train to pass along thel main track, Fig; 2 is a similar View showing the yparts in position to permit the train to pass along the main track to turn to the right, Fig. 3 is a plan view showing the parts in posit-ion to Permit the train coming around acurve from the right to continue along and turn to the right, Fie: 4 is a similar View Showing the parts in position to permit 'the train coming around the curve from the right to cross the main track and turn the left, Fig. 5 is a vertical transverse section partly in elevation on the line 5 5 of Fig. 1, Fig. 6 is an :elevation partly in section on the line 'S--Gof Fig. 1.

Referring particularly to the drawings7 1G"- and 11-11 represent the portions thev main straight track, the ends ot the former' terminating a suitable distance Specification of Letters Patent.

from the ends of the latter to provide a space for my switch mechanism, to be lat-er described. Extending from the right and left respectively of the tracks 1Q and 11, in one direction are the curves 12 and 18, while extending in the opposite direction from the first curves but to the right and left, are the curves 14 and 415, the inner ends of the curves being in line with one end of the straight tracks, on either side of the space before mentioned. A Vconcrete base 31 is formed under the space between the ends of the rails and extending to a suitable distance at each side and end thereof. Secured in said base under the ends of said rails are opposite sides of said space. Adapted to slide 'in these grooved plates are the tongue lcarrying plates 18, to which are secured 'the straight sections of railsl 2() Jand the curved rail sections 21 and 22. These short sections of rails have one end in line with `the main rails 10 and the curves 12 and 13, while their opposite ends terminate at a point about mid-way across the said space between the ends of the main rails, land 11. At the opposite side of the space is a second set of straight and curved rail sections 23, 24 and 25, having their inner ends arranged in line with the inner ends of the first-named straight and curved rail sections, and supported by the tongue carrying sliding plates 18 which slide on the grooved. plates 17. The sets of curved and straight rail sections are suitably held and spaced apartby the spacing bars 28, so that they may move together transversely of the track. For conveniencc in describing, these sets are marked A and B. Transverseiy in the center of the space between the ends of the main rails is a double grooved plate Q9, on which are adapted to slide the tongue carrying plates 30 and 3G at the inner ends o?? the rail scctions of and This upper portieri ot this plate lies Hush with the treads ot the .iils, and is formed with the notches 3S, to permit the flanges of the car wheels to pass thereover. The plates 1d 1S, 3G and SG are ais-o fori-ned with notches 1G", 15', SO and 56; for the saine purpose.

h/iounted hel lhe member and on either end rated and tcrrmlly *ihr which IGS ltrack are the stands 3.4, in which are journaled the ends of the shaft 33. On' one end of therod or shaft. 33 is a pulley around which passes the Wire cable' 37 AThese canins ,lead to a 'switch lever in the signal tower. The othei` device B has mounted thereonthe shattzi` journaled iii-theusupports or standards 34'," the shaft being valso provided with a pulley -35 and thev wirel cable 37', also leading to the signaltowen Upon rotation of either of the'shats 33 or 33', in either direction the groups ofV rail sections ril-and B may be inovedto the right or left to bring their rail sections in register with the .ends of each other, and withthe main tracks and curves. i

As clearly seen in Figi". 'l the straight sections are in'register with each other and with the main rails 10 and 1l so that v the train may pass along lthe main track. n F ig. 2- the straight sections of` B are in register withv the tracks 11, while A is moved to the lcft so that its curved sectionsv 21. and 22 register with the straight sections of B and the .curves 12, thus permitting a nortlibound trainlto leave the main track and pass around tlie curve to the right. A reverse inovinentfo'fv the members .A and B' will register so that the train will leave the main track and pass'aiound the curve l2 to the left. Upon moving both A and B to the cxtreme left position, as shown in Fig. 3, their curved sections will register with the curves 13 and l5 so that Ia train which may be coming from the south, around the curves 15 may continue north and east around the curve ll. A. movement of the ineinbersA and Vli'r to the extreme right will permit. al train to pass from the curve 14 around the curve 1Q. Should. a

train going'nr'th desire'- to pass from thc` curve 15 and around the curve 1Q, A. would be thrown to its extreme right post i lion, while B would be thrown toits extreme uit position, thus bringing the curved sec* ifoufs 2l into register with the curve sec( ions ol`I the member A., and the curved mein- 'wples of thls`patent`niay be obtained for five cents each, by addressing the A 1 Washington, l. C."

bers 25 of themember B into register with the curves 15.

By means of this switch il: is possible for a. train going north or soutlito be switched .east or West, the screw threads of the 533 and 33 holdingr the parts in diderent adjusted positions. ltQwill be seen' that a nmltitu'de of combinations may be had by moving the membersA and-B to various positions with respect` to the track and with veach other. Y

'hat is claimed isf 1L Inl av railroad-switch, a combination with a main track and curves extending to the right and left in both directions, of

transversely slidable members between the ends of said rails, straight and curved plate sections on these slidable members, and means formoving the said members trans- `versely of the track independently whereby said sections are capable of registering with the straight tracks and curved tracks.

In a railroad switch, a combination -`with a main track :1nd curves extrndingto ,the right and left. in both directx `ins, the ends whereby said tongucd members are movableV to tl'ierigght and lett to bring their straight and curved sm'ftions into alincnicnt with cach other and with the Istrahcght lil-:ichs and curved tracks. i
